    Another aircraft challenge. Do you know what
    this one is?

    I'm experimenting again with the Canon 75-300 USM IS. I posted a week or so ago that I had trouble getting it to focus on moving objects with the CPL on. Well, I had forgotten I put the CPL on on top of the UV filter. So I removed the UV filter, put the CPL back on and tried again. I got much better results. The majority of shots were in focus. One of the things I noticed was that the camera (a 1D) underexposes with this lens/CPL combo. But I also noticed that every shot I took in this series and a series of an airplane taking off just a few minutes earlier was that the lens was shooting wide open (f/5.6). I was shooting shutter priority mode at 1/125, to keep the props blurry. Just some interesting tidbits of info I'm discovering and trying to figure out how to use.

    I also discovered a habit I didn't know I had. When shooting these types of shots, instead of keeping the camera level, I seem to keep the airplane level, which makes the horizon crooked. I'd never noticed it before. Now that I can shoot a lot it stands out, to me, like a sore thumb. I've rotated this shot about 2 degrees and cropped just a bit to fix the rotation.

    Well here's the shot, an airplane just about to touch down. Anyone care to guess what it is? :)

    I've Seen One Of These Before...

    With that funky little winglet on the elevator. But I can't remember what it is. Reminds me of a DeHaviland.

    Here's a couple of hints. Tube and fabric, tri-tailed (sort of, got those two little rudders on the outside edge of the horizontal stabilizer).

    Sorry no guess from me, but I'm surprised that the UV filter caused a problem. I wouldn't do it because at that point the only thing it's doing is possibly reducing sharpness and introducing flare (more glass surfaces) - but wouldn't have guessed that it would cause AF troubles. Best way to solve problems like this is trial and error - sometimes it's hard to tell where the real problem is.

    The first time I shot at an airshow, I did the same thing. Most of my shots were off more than 2 degrees though - so I learned that lesson pretty quick!

    I know what it is
    It's a Bellanca Cruisemaster.

    A Winner!!
    You are correct! It's based here at the airport where I work. Not many airplanes look like this. Thanks for playing! :)
